Someone Leaving in a Public Chat Keep Me From Connecting to a Game

I've has this happen at least three times, and the disconnect cannot be coincidental.

I've been in games where I'm connected to a chat (TSM Chat), someone leaves during the champion select or before my loading screen finishes, and it instantly says I've lost connection to the game. I can go back to the client, talk to people in chat, but I cannot reconnect to the game. I quit the client and reconnect, come to find out someone has left the TSM chat. Maybe it's just my internet, but, I'm just putting this out there.
